I updated the NAV in my 04 x5 with DSP with a kit I bought from Ebay and I was able to now use 2 DVD disk as opposed to what the PO gave me.

We tried to update my friends 03 X5 4.6is build date 12/02 and it will not read the DVD map CD's after the update will only read CD's any ideas what the problem might be.

Thanks
Norm
